General description The machine to which the present invention is shownapplied, as illustrated and described in the applications cited,consists, in general, of a plurality of manipulative keys for enteringthe amounts to be registered, indicating mechanism for indicating theamounts registered and the total thereof, a plurality of totalizers foraccumulating the various items and transactions, and printing meanscontrolled so as to issue a receipt upon which is printed either asingle item or plurality of items, together with the total thereof. Abank of transaction keys, a bank of clerks keys and a totaltaking leverare provided for controlling the various elements of the machine, all ofwhich is fully shown and clearly escribed in the above mentioned Shipleyapplications and to which reference may be had for a completeunderstanding of the machine.

The machine to which the present invention is shown applied is adaptedfor use in places of business where it is desirable to registertransactions comprising a single item and transactions comprising aplura of items with the total thereof, and win.

it is desired to count the number of single item transactions, thenumber of items of a multiple item transaction, and the number ofmultiple item transactions entered into the machine; also where it isdesirable to count the number of transactions entered into the machineby each individual clerk.

Keg board The keyboard of the present machine is the same as that shownand described in the above mentioned applications, but more particularlythe parent case, Serial No. 687,305, to which reference is hereby madefor a full and clear description thereof. Only a brief description ofthe keyboard will be given herein.

The keyboard disclosed in the parent case comprises a plurality of banksof amount keys, not shown herein, a bank of clerks keys (F 3), a bank oftransaction keys 31 and 32 1), a key 33 for releasing the depressedtransaction key, total lever 34 (Fig. 13) for controlling the machine ontotal-taking and subtotal-taking operations, and a starting bar 35 (Fig.12).

Transaction keys.

The transaction keys 31 and 32 (Fig. l) and the transaction key releasekey 33 are mounted in a. common frame 36, supported in the machine bycross rods 37 and 38. Keys 31 are used in entering transactionsconsisting of two or more items and compel the totals thereof to beprinted. This is known herein as a multiple item transaction. The keys32 are used in entering transactions comprising a single item, knownherein as a single item transaction.

The keys 31 and 32 are held in their normal positions by springs, notshown, and are held in their depressed positions by a locking detent 39,supported at its upper end by an arm 40 and at its lower end by an arm41. Each of the keys 31 and has a pin 42 mounted therein, whichco-o-perates with a hook 13 on the detent 39 to hold the key depressed.After the key 31 or 32 has been depressed, the detent 39 is returned toits normal position by a spring 44:, at which time the hook 43 engagesthe pin 12 and retains the key in its depressed position.

The transaction keys 31 and 32 are not released automatically during anoperation of the machine, as are the clerks keys and the amount keys.Keys 31 and 32 can be released only by depressing another one of thetransaction keys 31 or 32, or by depressing the transaction key releasekey 33. This key is provided ith a pin 42, which co-operates with anangular lug 45 on the detent 39 to move the detent down and release thedepressed transaction key. There is no hook 43 opposite the key pin 42of the transaction key release key 33, and therefor, this key willreturn immediately to its outward or normal position.

Transaction difi'crcntial mechanism Associated with the bank oftransaction keys is a differential mechanism (Fig. 1) provided for thepurpose of adjusting the printing and indicating mechanisms, selectingtransaction special counters, and controlling the various elements ofthe machine for registering single item and multiple item transactions.

This differential mechanism includes a differentially movable arm (Fig.1), given a variable movement on each operation of the machine. Pinnedto the shaft 51, which is the main drive shaft of the machine, is a pairof cams 52, co-operating with two rollers carried by a (shaped lever 5a.The lever 5a is pivoted on an irregularly shaped support plate or hanger55, supported in the machine by two rods 56. At its upper end the lever54- is connected by a link 57 to a driving segment 58, pivotally mountedon a stud 49, carried by the hanger 55. The cams 52 receive oneclockwise rotation on each operation of the machine, which, through themechanism just describet, rocks the segment 58 first clockwise and thencounter-clockwise to its normal position. The segment 58 receives thisinvariable excursion on each operation of the machine. The arm 50 isconnected to the segment 58 by a latch 59, the foot of which engages ashoulder on the segment 58, and is held in this position by a spring 60.

The latch 59 (Fig. 1) is supported on the arm 50 by an arm 61 and a bellcrank 62. As the segment 58 is moved up, the arm 50 is carried with ituntil an end (33 of the bell crank 62 strikes the end of a depressed keyand is rocked counter-clockwise, disengaging the foot of the latch 59from the shoulder on the segment 58 and engaging a nose 6d on the latchwith a notch 65 formed in a plate 66, supported by one of the rods 56and the upper end of the hanger The segment 58 continues its regularexcursion and on its return movement, as the shoulder thereon arrivesopposite the foot of the latch 59, the spring 60 will act to disengagethe nose (it from the plate 66 and reengage the latch with the segment58. At this time a stud 67 mounted in the arm 50 is engaged by a surface(38 on the segment 58 which returns the arm 50 to its normal position.

A beam 86 is associated with the differential mechanism fordifferentially adjusting the printing mechanism, selecting totalizers,and controlling the various elements of the machine. The beam 86 ispivoted on the arm 50 and at its right hand end is bifurcated tocooperate with a pin 87 in a link 88. At is lower end the link 88 isconnected to an arm 89 secured to one end of a sleeve 102 surrounding arod 103. A roller 104 is mounted on the Y-shaped lever 54 to adjust thebeam as is old and well known in the art.

The key pins 42 of the transaction keys 31 .and 32 (Fig. 1) also engagea setting bar 7 O,

which operates an interlock between the transaction keys and thestarting bar. The bar is supported at its upper end on an arm 71 (Fig.11) and at its lower end on an arm 72 1). Mounted on the arm 71 is a pin73 which engages an upwardly extending arm 74 of a yoke 75 pivoted onthe shaft 76. As a transaction key 31 or 32 is depressed, the key pin 42(Fig. 1) will engage an inclined wall 77 of the setting bar 7 O and rockthe bar to the left, to rock the yoke counter-clockwise (Fig. 11). Thearm 74 is maintained in engagement with the pin 73 by a spring 69. Asthe yoke 75 rocks counter-clockwise it carries with it the releasingpawl 78, pivoted on the shaft 76 and held in engagement with the yoke 75by a spring 79. The pawl 78 has a projection which normally lies in thepath of a flattened stud 46 mounted in an arm 47, pinned to a machinereleasing shaft 48 adapted to be rocked clockwise, as will be laterdescribed, when the starting bar 35 is depressed. An interlock isthereby formed between the transaction keys 31 and 32 and the startingbar 35, so that if the starting bar is operated without depressing atransaction key, the machine will not be released for operation. If,however, the transaction key is depressed in its proper sequence, theprojection on the pawl 78 will be out of the path of the stud 46 whenthe starting bar 35 is operated to release the machine, as will behereinafter described.

In entering a multiple item transaction, the operated key 31 should belocked in depressed position, and all other transaction keys lockedagainst depression, until the completion of the entire transaction.

This result may be conveniently obtained by arranging the inclined wallsof those recesses in the setting bar 70 which lies beneath the multipleitem keys 31, so that upon depression of a multiple item key 31,

the setting bar 70 is given a greater extent of movement than isimparted to it by the single-item keys 32, and by providing the arm 72to which the lower end of the setting bar 70 is pivoted, with a notch80, engageable by a: locking bail 81 journaled on a shaft 83.

lVhen a single-item key 32 is depressed, the setting bar 70 is notshifted a sufficient distance to swing the notched arm 72 far enough tobring th notch 80 into the path of will shift the setting bar 70 and itsarm 72 to such an extent that, upon complete depression of the key andthe restoration of the detent 39, and its arm 41 to locking position,the notch 80 in the arm 72 is located in. the path of the locking bail81, preparatory to tl e entry of the edge of the locking bail 81thereinto.

An arm 82 pivoted on the shaft 83 is fast with the locking bail 81 tocontrol the latter. The inner free end of the bail arm 82 extendsinwardly into the path of a stud projecting from the usualdifferentially movable arm 50, which stud normally maintains the bailarm 82 and the locking bail 81 in idle position a inst the tension of asprin: 84 connected Wl-Lll a stud 101 on the arm 82, which tends to rockthe arm 82 and locking bail 81 counter-clockwise toward the arm 72,

Depression of an item key, and amount keys, followed by an operation ofthe machine, rocks the differential arm 50 clockwise, in the well knownmanner, to select proper totalizer, and in so doing, the differentialarm 50 releases the bail arm 82 to the action of the spring 84, whichrocks the arm 82 and its locking bail 81 counter-clockwise, to enter thebail 81 in the notch 80 and hold the depressed multiple item key 31 inits depressed position throughout two or more operations of the machine.

The extent of travel permitted the locking bail 81 w 1 11 it enters thenotch 80, positions the bail beneath the arm 41, and thereby locks allof the keys in the transaction bank depressi V711 a sirnein key 32 isdepressed, and the machine is operated, the limited travel permitted tnelocking ball 81 is such that the free end of the bail arm 82 remains inthe path of the stud 85 when the bail con tacts the unnotehed end of thearm 72 so that upon the return of the differential arm 50 at the end ofthe operation, the stud 85 contacts the bail arm 82 and restores it,together with the bail 81, to idle posi ion (as shown in Fig. 1). Butwhen a multiple item key 31 is depressed, and the machine is operated,the extent of travel of the bail 81 withdraws the free end of the arm 82from the path of the stud 85 on the differential arm 50.

Therefore, to effect the release of the depressed multiple-item key 31,and the restoration of the locking ball 81 to its idle position, thetotal lever 34 (Fig. 13) is provided with a cam slot 90. After all theitems of a multiple-item transaction havebeen entered in the machine,the total lever 34 is manually shifted from its normal add position tothe item total position, and after the total is printed, the total leveris restored to its normal ads position. A roller 91 carried on one armof an intermediate lever 92 pivoted at 93, enters the cam slot in thetotal lever, the opposite ISO arm 95 of the lever 92 having formed onone edge thereof a cam recess 1 12. A link 9% also pivoted at 93 andoverlying the arm 95 of the lever 92, has a comple'ientary cam recess 97formed in its edge, which cooperates with the cam recess 103 to con'tut-e a cam slot. A spring 96 connects a stud 1 13, on the link with thearm 95 of hold these parts together, with the stud 1 13 in contact withthe upper end of the arm 95. This arrangement provides a texible cammechanism which will yield to prevent injury to the machine in case thesh ft 83 is locked by a depressed key at the time the total levershifted n its add position. A crank 99, fast on the shaft 83, on whichthe bail carrying arm 82 is pivoted, carries a roller entered in the JOcam slot formed by the complen'ientary recesses 103 and 97 of the arm 95and the lever 92 respectively.

When. the total lever its add position to our total position, its camslot 90 rocks gii lever 92 in a counter-clockwise direction, and the arm95, together with the link 9 1, rocks the crank 99 and shaft 83 in aclockwise direction.

A tappet 100 1), fast on the shaft 83 is thereby rocked to contact astud 101 on the bail arm 82.

As is customary in machines of the ty e to which this invention isapplied, a total taking operation includes two cycles of r tation of themain drive shaft 51 of the machine, during the latter part of the firstof which cycles, the shaft 83 is automatically given a second step ofrotation in a clockwise direction (by means later described) whichpresses the tappet 100 against the stud 101 on the bail arm 82 to rockthe bail arm 82 clockwise sufiiciently to return the free end of thebail arm into the path of the stud 85 of the differential arm 50, whilethe latter is at a point some distance above the bail arm 82, so that asthe differential arm is restored, its stud strikes the free end of thebail arm 82 and withdraws the locking bail 81 from the notch 80 in thearm 72 to permit the release of the depressed multiple item key 81.

Mechanism will now be described for giving the shaft 88 the secondclockwise movement mentioned above. This mechanism comprises the cam 105(Fig. 12) freely mounted on a stud supported by the side frame of themachine and adapted to cooperate with a roller 107 mounted in a pitman108. The roller 107 is normally held in a notch in the groove and iswithdrawn from its ineffective position, in the notch, into an effectiveposition in the cam groove by the above described movement of the totallever 34. The pitman 108 is guided on the stud 106, and at its left handend is pivoted to one arm of a lever 109, pivoted on adjusted from astud 110, supported by the side frame of the machine. The opposite armof the lever 109 is connected by a link 111 to an arm 112 pinned to theshaft The cam 105 receives one counter-clockwise rotation on totaltaking operations which moves the pitman 108 first to the 1d rocks thelever 109 clockhe link 1 11 and arm 112, slightly clockwise to re s endof to bail arm 82 into the path of the stud 85 on the differential arm,s above describeo. The pitman is then restored to the position to whichit was moved by the tot; i lever 3 1, as described above.

Clerks keys The present machine is provided with f ur clerks keys 30(Figs. 3 and 4:) .i-ounied a frame 115 (Fig. 4) supported bv'the rod 87and a rod near the left :1 side ofthe machine. The keys 30 whendepressed are so retained by means of a detent 117 slidably mounted ontwo screw studs 118, and the detent is moved toward the right when oneof the keys is depressed. The detent 117 is spring urged toward the leftand after the key has been depressed, a shoulder 119 engages a pin 120mounted in the key. The depressed. clerks key is returned to its normalposition by a spring, not shown, near the end of a single item operationand near the end of the second cycle of a total-taking operation. Thedetent 117 is moved to release the key by a bell. crank 121 (Fig. 41),one arm 122 of which is adapted to engage a pin 123 on the detent. Thebell crank is pivoted on a stud mounted in the frame and is held in itsnormal position by a spring 12 1. The other arm 125 of the bell crank isadapted to be engaged by the pin 126 carried by segment gear 127 pivotedon a sleeve 128. As the segment gear moves clockwise, the pin strikesthe arm and moves it in a coun tor-clockwise direction. As the pin 126passes off the arm, the bell crank will. be returned to its normalposition by the spring 12%. lVhen the segment gear 127 is movedcounter-clockwise to its normal position, the pin 126 will strike therear end of the arm 125 of the bel crank, thereby rocking the arm 122clockwise to engage the pin 123, thus moving the detent 117 to theright. This movement of the detent disengages the shoulder 119 from thepin 120, permitting the depressed key to be returned to its normalposition. .Vhen the pin 12G passes oil the arm 125, the spring 121 againreturns said arm to its normal position.

Mechanism is provided to compel the depression of a clerks key beforethe machine can be released for operation. Pinned to the shaft 18 is anarm 130 (Fi 1) normally contacting the underside of a pin 131 carried bya releasing bar 132, slidably mounted on the screw studs 118 andretained in its normal position by a spring 129. As a clerks key isdepressed the pin 120 will engage an inclined edge 133 of the releasingbar move the bar toward the left to withd .w the pin 161 from the pathof the arm-130. The shaft 48 is then free to be rocked, as willhereinafter be described, to release the machine for operation.

Thegear segment 127 has a rearwardly extending arm 134 (Fig. 4),connected by a link 135 to a lever 136 (Fig. 14), pivoted on a'stud 137,projecting from the printer frame, not shown. The lever 136 has adownwardly extending arm 138 to which is attached a spring 139. Thisspring through the lever 136 and link 135, imparts to the gear segment127 its clockwise move ment. The clockwise movement of the lever 136 andconsequently the clockwise movement of the se ment 127 is limited by astud 140 mounted in the printer frame, not shown, in the path of an arm141 on the lever 136.

Mechanism will now be described for restoring the gear segment 127 toits normal position. A pair of cams 145 (Fig. 8) pinned to a shaft 146co-operates with two rollers 1 47 carried by the forked arm of a lever148 pivoted on a stud 149 supported by the side frame of the machine. Atits upper end the lever 148 is pivoted to a slide 150 which is guided bya stud 151 mounted in the printer frame. At its left hand end the'slide150 is adapted to engage the pin 126: carried by the segment 127. Thecams 14-5 receive one clockwise rotation on each operation of themachine, which moves the slide 150 first to the right and then to theleft to restore the segment 127 to its normal position.

The shaft 146 is driven by a pinned thereon, meshing with a gear 153,journaled on a stud 154. The gear 153 meshes with a gear 155 pinned tothe shaft 51, which is the main drive shaft of the machine. A gear 156pinned to the gear 153 is is used only when the machine is operated byan electric motor.

The gear teeth on the segment 127 (Figs. 4', 8,9,10 and 14) are not usedin the present invention, but it is thought that a brief description oftheir use as illustrated and described in the above mentionedco-pendi'ng applications will be helpful. This segment is adapted tor'eceivea long and a short oscillation to impart to the issuing receipta long'feed and ashort feed. The length of thefeed is governed accordingto the character of the transaction. The movement of the feedingmechanism on a single item transaction is equal to the greater movementof the segment 127. hen an item of a multiple item transaction is engear152 tered, the feeding mechanism will move a distance equal to theshorter movement of the segment 127.

It is therefore to be understood that when an individual item of amultiple item transaction is entered into the machine it is not desiredthat the clerks key should be released. A description of the mechanismfor controlling the release of the clerks keys will now be given.

Pivoted on a shaft 160 is an arm 161 (Figs. 8, 9, 10 and 14) whichis-operated by a flexible drive member on account of the overlapping oftime in the operation of the segment 127 and the arm 161. Projectinglaterally from the arm 161 is a pin 162 projecting between two arms 1'63and 164 (Fig. 14) held in contact with the pin by a spring 165 stretchedbetween the arms. These arms are driven by a pin 166 carried by a lever167 which is pinned to the shaft 160. When the arm 161 is movedcounter-clockwise to the position shown in Fig. 9 the hook portion ofthe arm will be in the path of the flattened stud 168 carried by thesegment 127. lVith the arm 161 in this position, the segment 127 will belimited to a shorter movement. The arm 161 is placed in this position bymechanism controlled from the transaction keys.

Secured to a segment lever 170 (Fig. 8) is a cam arm 171. The cam arm171 is adjusted under control of the transaction keys 31 and 32, whichcontrol the differential positioning of the link 88 (Fig. 1). arm 89,and sleeve 102, in the manner before described. Fast to the sleeve 102is a segment 113 (Fig. 8) meshing with the lower teeth. of the segment170 loose on the stud 114, to which the cam arm 171 is also secured. Theouter edge of the cam arm 171 contacts a roller 172 carried by an arm173 loose on the shaft 160, (Figs. 8, 9 and 10). This cam arm 171 has alow edge 174 and a high edge 175. In single item transactions the highedge 175 (Fig. 8), of the cam arm is in contact with the roller 172.with the arm 161 in its ineffective position in relation. to theflattened stud 168. With the arm 161 in this position. the depressedclerks key will be released on each sin le item transaction operation.In a multiple item transaction operation the cam arm 171 given acounter-clockwise movement sufficient to bring the low edge 174 of thecam arm 171 opposite the roller (Fig. 9 and 10).. whereupona spring 176.stretched between arm 177 pinned to the shaft 160 and a pin projectingfrom the printer frame. will rock the arm 161 counter-clockwise into thepath of the flattened stud 168. In this po sition the arm 161 will limitthe clockwise movement of the segment 127. This limited movement of thesegment is not suflicient to carry the pin 126 past the arm 125 of thebell cank 121, for which reason the a'm 122 will not receive a clockwisemovement and the clerks key will not be released when the items of amultiple item transaction are entered.

After the last item of a multiple item transaction has been entered, thetotal-taking lever 34 (Fig. 13) is moved to the item total position,which imparts an initial movement to the shaft 83, as previously described.

Secured to the shaft 83 is an arm 180 (Figs. 8, 9, and 10) connected toone end of a pitman 181, which at its opposite end is bifurcated toslide upon the shaft 160. The pitman 181 carries a roller 182 whichengages an arm 183. pinned to the shaft 166. The initial clockwisemovement of the shaft 83 will, through the means just described. rockthe arm 183, shaft 160 and arm 161 clockwise to the positions shown inFig. 10v

As the initial movement of the shaft 83 is not sufiicient to move theroller 172 out of the path of the high edge 175 of the cam arm 171,which is moved by the differential mechanism of the transaction bank oneach cycle of operation, it is necessary to provide means for giving theroller 172 additional movement. An arm 184 (Figs. 8, 9 and 10) pinned tothe shaft 83 is connected to one end of a link 185. which at itsopposite end carries a roller 186 engaging a slot 187 in the arm 173,loose on the shaft 160 and a slot 188 in the arm 177 pinned to the shaft160. As the shaft 83 is given its initial movement the roller 186 movesdownwardly in the slots 187 and 188 (Fig. 8) causing the arm 173 to moveclockwise, to a position in which the roller 172 is clear of the cam arm171, (Fig. 10). WVhen the shaft 83 receives the additional movementhereinbefore described, the roller 186 continues its downward movementin the slots 187 and 188 without imparting additional move ment to thearms 173 and 177, the lower parts of the slots being parallel each withthe other. This additional movement of the shaft 83 imparts additionalmovement to the arm 183 through the roller 182, which as additionalclockwise movement to the hooked arm 161, placing it in ineffectiveposition. With the hooked arm 161 in its ineffective position, thesegment 127 will be 'ierinitted its full length of movement during thesecond cycle of a total-taking operation, which will position the pin126 to the right of the arm 125 of the bell crank 121. When the segment127 is returned to its normal position, the arm 122 and the detent 117will be moved to release the depressed clerks key.

OZeHcs Iceg counter A counter 178 is provide ber of transactionsregistered by each clerk. The counters are of the usual step-by-steptype and are mounted in a frame 179 located to the right of the clerkskey f 'ame 116. These counters are operated during a single itemtransaction and during the second cycle of a total-taking operation of amultiple item transaction.

For the purpose of selecting the counters 178 for actuation each key 30is provided with a pin 189 (Figs. 3 and 1) engaging an elongated openingin a link 190, which is connected by a pin 191 to an operating link 192,for actuating the counter this operating link being connected to an arm193, freely mounted upon the counter shaft 19 1-. The arm 193 carries adifferentially tined pawl 195, which engages ratchet wheels 196 tooperate the counter in the usual way. Spring actuated retaining pawls197 prevents retrograde movement of the counter wheels. The pins 191engage slots 198 formed in a reciprocating driver 199 common to all thecounters, pivoted at its upper end on an arm 200 and at its lower end onan arm 20].. The arms 200 and 201 are pivoted on the frame 179. Asliding counter-selecting bar 211 (Fig. 3) is provided with projections212, 213, 21 1 and 215 which provide obstructions co-operating with thelower ends of the connecting links 1.90, actuated by the keys, to enablethe reciprocating driver 199, through the selected operating link 192,to operate the tined carrying pawl 195 of the counter corresponding tothe key depressed. The selecting bar 211 is guided in its slidingmovement on two screw studs 216, which engage slots formed therein. Thelower key 30 (Fig. 3) is shown depressed with its connecting link 190moved into engagement with the obstruction 212. As the driver 199 movestoward the left the operating link 192 is forced toward the left, whichcauses the tined carrying pawl 195 to move the ratchet wheels 196 onestep of movement. The selecting bar 211 is connected at its lower end bya stud 217 to an arm 218, pinned to the shaft 160. The arm 218 issecured by a rivet 219 to the arm 177, which is oscillated to adjust theselecting bar 211 by mechanism under control of the transaction keys, aspreviously described.

In a transaction involving two or more items, the bar 211 is movedtoward the right to an ineffective position during the first itementering operation and is returned to its effective position as shown inFig. 3 during the second cycle of a total-taking operation, all of whichwill hereinafter be described. The clerks counter may be reset to zeroat any time, by manually turning the usual disc 220, secured to thecounter shaft 1941, all of which is old and well known in the art.

Mechanism will now be described for giving the driver 199 itseci-procating movement. The arm 200 (Fig; which supports the driver atits upper end has a slot formed therein which co-operates with a pin 221mounted in an arm 222, free on the shaft -6. The arm is rigidlyconnected to an arm (Fig. 5) by means of a hub 225. The arm 221 has apin 22o ionnted therein, which co operates with a slot formed in an arm227, similar to the arm 200, which supports one end of ""ie driver 199.The arm- 227 supports the u icr end of anoperating bar which at itslower end is supported by an arm (Fig. (i). The arm 229 a downwardly ending finger 280 upon which is mounted a pi co-operating with a slotformed in the end of an arm 282" supported on the front rod 5.6. It canbe clearly seen that a counterclockwise movement of the arm will thronglithe mechanism just described, rock the arm 290 clockwise and move thehive 199 to the left. Pivoted to the arm (Figs. 6 and? 7) is a link.vhich at opposite end carries a pin projecti into a right angle openingformed the arm 236', pinned to a shaft 237. At its opposite end theshaft 237 has pinned hereto an arm 238 (Fig. to which is pivoted apitman: adapted at its right hand end to slide on the shaft 51. Thepitman 25);) carries a roller projecting into cam groove'2l'1 formed inthe side of a gear 25-2 pinned: the shaft 51:. 1t will be remen beredthat the shaft 51 is the main d e shaft of the machine and receives onewise rotation on each cycle of ope; The cam groove 211 is so shaped asto give the pitmair239 a movement first to t is ii 3 and then back toits normal position, it through the arm will rock the s" firstcounter-clockwise and hen c normal. This rocking movem' it shaft 237will through the arm 6 and 7-) and link 2333 give'the arm its rocking.-movement described above.

As it is desired. to advanced the clerks counter one step on each singleitem transaction, and one step on each multiple item transaction only,it is necessary to provide means fordisablingthe ole ks counteroperating: mechanism when regntcring the items ofa multiple itemtransactionand on certain total-taking; operations. T his disablingmechanism. will now be described.

It will be recalled that the cam arm 1. (Figs. 8, 9 and 10)dilierentially positioned under the influence of the tra saction keys 31and 32. The high roller 1.72. As shown in Figs. 3 and 8, these parts arein position for a single item entering operation. When, however, a.multiple item key is depressed and the cam arm 171 is rockedcounter-clockwise to the position shown in 9, the spring 176 will rockthe arm 177 counter-clockwise. This counter-clockwise movement of thearm 177 will, through the arm 218 (Fig. move the counter selecting bar211 to the right, moving the projections 212, 213, 214 and 215 fromtheir effective positions opposite the key actuated connecting links190. Vith the selecting bar 211 in this position, the connecting links190 will be slid idly over the pins 189 when the driver 199 is moved tothe left. Likewise the pins 191 will slide idly toward the bottom of theslots 198 and the link 192 will not be operated to advance the selectedclerks counter.

it will be recalled that when the machine is operated with a multipleitem key depressed, the cam arm 171 (Fig. 9) is adjusted to the positionshown in Fig 9. This positions the low edge 1 7 1 on the cam arm beneaththe roller 172 on the arm 173, which permits the spring 176 to rock thearm 178 and the arm 177 countcr-cloclnvise about the shaft 160, whichthrough the arm 218, will in ve the selecting bar 211 3) to the right.After the last item of a multiple item transaction has been entered inthe machine, the total l ver 1:3) is adiusted to the item totalposition. This movement of the total lever 31, it will be recalled,gives the shaft 83 an initial clock wise movement. This movement of theshaft 83 rocks the shaft 169 and consequently the arm 177 clockwise, asdescribed above, to move the selecting bar 211 to the left to itse'l'l'ective position. It is, however, desirable to disable theoperation of the clerks counter on the first cycle of anit'emtotaltaking operation. The following mechanism h. s been provided toaccomplish this:

Pinned to theshaft 83' is an arm 2-15 (3) having formed therein a slot 216 into which projects a'pin 2-17 carried by one arm of a three-armedlever 2&8. The'lever 2-18 is pivoted on theshaft 237 and has a down-.vardly extending arm 219 formed to engage a pin 250 carried on adownwardly extending arm 251, of the lever 252 also pivoted on the shaftAn upwardly extending arm 25 of the lever 252 carries a pin proiectinginto a slot formed in the link 7). The shaft is given an initialclockwise movement by the movement of the total lever This movement ofthe shaft 83 will move the arm 2415 counter-clockwise a distancesufficient to cause the cam slot 246 to rock the lever 248counter-clockwise, which through the arm 24.9 and pin 250 will rockthelever 252 also counterclockwise. The counter-clockwise movement ofthe lever 252 through the pin 254 will rock the link clockwise about itspivot in the arm a distance sufficient to position the pin in the angleof the opening 235 in the arm 236. In this position the arm 232 will beineffective to shift the driver 199 to the left, as described above.Just before the second cycle of a total-taking operation the shaft 83 isgiven a second clockwise movement as hereinbefore de scribed. Thissecond movement of the shaft 83 and the arm 245 through the cam slot 246will rock the lever 248 clockwise to its normal position. At this time aspring stretched between one arm of the threearmed lever 248 and thedownwardly extending arm 251 of the lever 252 will rock the lever 252clockwise to restore the link 2333 to its normal position thus movingthe pin 234 into the lower part of the opening 235 in the lever 236.Therefore, on the second cycle of a total-taking operation the arm 236is effective to operate the special counter as hereinbefore described.

It is not desired to advance he clerks special counter when reading orresetting the totalizer selected under control of the transaction key32. The mechanism will now be described for disabling the clerks counteroperating mechanism on such totaltaking operations.

A cam arm 255 (Figs. 7 and 13) pinned to the shaft 103 near its lefthand end, is constantly urged counter-clockwise by a spring 256. The camarm 255 is retained in its normal position by a roller 257 carried on alever 258, pivoted on the front rod 56, engaging a cam block 259 rivetedon the total-tale ing lever 34. The lever 258 is bifurcated at its lowerend to engage the pin 260 carried by an arm 261 pinned to the shaft 103near its right hand end. When the total lever 34 is moved two stepscounter-clockwise to prepare the machine for resetting the totalizerselected by one of the keys 32 an inclined edge 262 of the block 259 isbrought opposite the roller 257 whereupon the cam arm 255 is rockedcounter-clockwise under the influence of the spring 256. Thecounter-clockwise movement of the cam arm 255 will, through a pin 264(Fig. 7) carried on the lever 265 rock the lever 265 counter-clock wise.A downwardly extending arm of the lever 265 engages a pin 266 mounted onthe lever 252, previously described, and rocks this leverC01l1lL'61--ClOClCWlSQ, which in turn rocks the link 233 clockwise toremove the pin 234 from its effective position to its ineffectiveposition in the opening 235 in the arm 236. The driver 199 will not beefiected by the movement of the arm 236, as previously described. Themovement of the total lever 34 (Fig. 13) to its add position willrestore the parts just described, to their nor mal effective positions.WVith the total control lever 34 in its add position and when it ismoved one step counter-clockwise to prepare the machine for resettingthe multiple item totalizer the lever 258 is held in the position shownin Fig. 13 by a concentric surface 267 of the block 259. In thisposition the cam arm 255 is ineffective to disable the clerks counteroperating mechanism.

Depressing one of the clerks keys (Figs. 2 and 4) directly positions atype having characters corresponding to the clerks keys by the followingmeans. The pins 120 on the key shanks co-operate with a lever 272 (Fig.2) to rock this lever clockwise and counter-cloclnvise according to thekey depressed. This lever is pivoted on a stud 27 3 mounted in the key'ame 115. One end of the lever 272 is bifurcated to engage a pin 274carried by one arm of a bell crank lever 275 pivoted on a stud 276,supported in the key frame 115. arm of the bell crank lever is connectedby a link 277 to an arm 278 secured to one end of a sleeve 279, to theother end of which is secured the clerks type wheel 270.

Operating mechanism The machine, as shown, is operated manually by thecrank 280 (Fig. 12), connected to a gear 281, meshing with a gear 282,which in turn meshes with the gear 242 pinned to the main drive shaft51, previously decribed. The ratio of the gears is such that twoclockwise rotations of the crank 280 and gear 281 will give one-half ofone counterclockwise rotation to the gear 282 and one clockwise rotationto the gear 242 on the main drive shaft 51. The machine may also bedriven by a motor which is not shown or described herein, as it forms nopart of this invention.

The machine is released for operation by depressing a clerks key 30(Fig. 3), a trans action key 31 or 32 (Fig. 1) and the starting bar 35(Fig. 12). This permits the releasing shaft 48, previously mentioned, tobe rocked clockwise to release the machine for operation in a mannerfully illustrated and described in the above mentioned co-pendingapplications.

The shaft 48 normally tends to rock clockwise under the influence of aspring 285 compressed between the bottom of a slot in a link 286 and theshoulders of two identical spring pilots 287 carried by an arm 288pinned to the shaft 48. Also pinned to the shaft 48 is an arm 289 whichcarries a flattened stud 290. A pawl 291 pivoted on a stud mounted inthe side frame 292 of the machine normally lies in the path of theflattened stud 290,

thereby holding the shaft 48 in its normal position against the pressureof the spring 285. A pin 293 carried by a slide 294, upon which isremovably mounted the starting bar 35, projects into the bifurcatedportion of p The other i 'an arm 295, connected by a link 296 to adownwardly extending arm of the pawl 291. Through this mechanism,depression of the starting bar 35 rocks the pawl 291 counterclockwiseout of the path of the stud 290 whereupon the spring 285 expands to rockthe shaft 18 clockwise to release the machine.

Mechanism for restoring the shaft 48 to its normal position near the endof each operation of the machine will now be described.

Cut in the side of the gear 282 is a cam groove 300 into which projectsa roller 301 carried by an arm 302, pivoted on the stud 110. At itsright hand end the arm 302 is provided with a pin 303 engaging a notch306 in an opening 30 1 in the link 286 previously mentioned. The camgroove 300 is shaped to rock the arm 302 clockwise and back to itsnormal position near the end of each cycle of operation of the machine.It

will be recalled that at the beginning of the operationthe arm 288 isrocked clockwise by the spring 285 which positions the stud supportingthe spring pilots 287 at the upper end of-the slot in the link 286. Theclockwise movement of the arm 302 just described, will through the pin303, link 286 and arm 288 rock the shaft 83 counter-clockwise slightlypast its normal position whereupon the starting bar 35, pulled by aspring 305, returns to its normal position, which through mechanismhereinbefore described restores the pawl 291 to its position in thepath'of the stud 290. The shaft 48 then rocks clockwise until the stud290 rests against the pawl 291, in which position the parts are ready tobe released for another operation. The pawl 78 (Fi 11) is restored inasimilar manner.

As on total-taking operations the machine receives two cycles ofoperation, it is neces sary to prevent the restoration of the parts justdescribed'to their normal positions near the end of the first cycle andmechanism provided therefor will now be described.

Referring to Figs. 12 and 13,it will be remembered that the shaft 83 isgiven a preliminary clockwise movement when the total lever 34 is movedto prepare the machine for a totaltaking operation. This movement of theshaft 83 through the arm 112 (Fig. 12), link 111 and lever 109 mores thepitman 108 to the left a distance sufiicient to remove the roller 107thereon from the notch in which it normally rests, and into'effectiverelation with the cam groove 105. This initial movement of the pitmanalso moves a coupling slide 309 to couple the cam 105 to the gear 282 insuch a manner that they will be rotated in unison. A further descriptionof the coupling slide 309 is not thought necessary, as it is old andwell known in the art and shown in the Fuller patent, No. 1,242,170. Atits right hand end the pitman 108 is provided with a stud 310co-operating with a slot 311 formed in the lower end of the link 286.Upon the initial .iovement of the lever 34, the pitman 108 and stud 310shift the link 286 to withdraw the notch 306 therein from the pin 303and position a shoulder 307 into the path of the pin 303. During thefirst cycle of operation of a total-taking operation the cam 105 willgive the pitman 108 a movemen to the left, and the stud 310 will rockthe link 286 clockwise and posi tion the lower end 308 of the opening304 therein in the path of the pin 303. In this position the tester ngarm 302 is ineffective on its downward movement and will not lower therestoring link 286. During the second cycle of the machine the link 286is restored to the position into which it was set by the total lever 34,that is, with the shoulder 307 in the path of the pin 303, and the shaft48 is restored when the pin 303 strikes the shoulder 307 upon thedownward movement of the restoring arm 302. The restoring movement giventhe shaft 18 the end of a total taking operation is not as great asduring adding operation-s since the shoulder 307 is located below thenotch 306. This is necessary due to the structural relations of certainelements not disclosed herein, but which are fully disclosed in theFuller patent referred to.

Totalieers The machine is provided with a plurality of totalizerssupported, respectively, in three frames. 315, 316 and 317, mounted onshafts 318, 319 and 320, respectively. The totalizer frames 315 and 316are slid-able laterally in the machine, to select the transaction andclassi cation totalizers mounted thereon. The upper totalizer frame 317carries a nonshiftable totalizer used only to accumulate the totals ofmultiple-item transactions and is rocked into mesh with the totalizeractuators under the control of the transaction keys in the'manner fullydisclosed in the patent application. To select the totalizers in the twolower frames 315 and 316, there is provided the following mechanism:

Rigidly connected to the arm 89 (Fig. 1), which it will be remembered isdifferentially positioned under control of the keys 31 and 32, is a.segment gear 321, meshing with a rack 322 secured to a slide 323. Theslide 323 is slidably mounted on two studs 32 i and has a flange 325 ateach end. Formed in the flanges 325 are cam slots, not shown, into whichproject rollers, also not shown, carried by slides 326. These slides 326cooperate with the totalizer frames 315 and 316, to slide these frameslaterally in the machine, for the purpose of selecting the totalizers,all of which is fully shown and described in previo sly mentionedapplications.
